How many total wires are on this device. The old Honeywell device I am replacing has 3 and I need to make sure this will work.

It has three wires: black (line), white (neutral), and blue (load). Note, however, that it does not adjust itself automatically for sunrise/sunset and daylight savings time, which are features that I wanted. I therefore replaced it with a Honeywell RPLS741B1007/U, which works great.

I had to look up the 6280 at Honeywell's website. It does not have any type of wireless transmitter or receiver built in. You would have to purchase a wireless receiver to attach to your security system if you don't have one already. That is the determining factor, do you have wireless devices already? If you do; they have to be 2800 series devices. If the answer to both is yes, than yes the remotes can be programmed into the security system.

Mary, I am not an electrician. I also did not have corresponding yellow wires, but did have two wires that went into the unit I replaced. I just connected to the two wires going into old thermostat and I was good to go.

Sorry - I have not as yet installed the thermostat. Honeywell product support should be able to answer your question.

John: With a 3 wire theromstat you most likely have 1 stage heat, 1 stage cool and common. I am assuming you have 3 thermostats in the house as well as 3 HVAC units or only one HVAC unit with 3 zones attached to it. If the former, 3 separate HVAC units, then I believe you will need 3 wireless set-ups. If only one HVAC unit with 3 thermostats then I am reasonably sure you will need a Honeywell wirelessTrue Zone panel and 3 wireless thermostats. Based on my research, Honeywell makes the best wireless set up--but it can become pricey. Hope this helps. Steve

No- this is a one wire alt. They did offer a 3 wire but it was a different part number.

Yes. That should work fine. This device just needs internet access. Once connected you log onto your Honeywell account and finish the provisioning to reference that gateway to your system.

I bought the thermostat today, and found out that my original setup had only four wires; missing C wire. But Honeywell have a video showing you how to substitute G wire for C wire. https://www.youtube.com/watch?v=F05lIaNTMB4 Basically, G wire is for operating Fan only mode (no heat / cooling). You loose the ability to use FAN only to power this thing. You have to change wire on the back plate as well as in the A/C-Heater. I'm not very skilled, but I was able to do it, just following the video.

Something must not be set up properly. I would contact Honeywell Customer Support. 1 (877) 841-2840

The same sensor that I received has only two wires. READ CAREFULLY THE INSTALLATION INTRUCTIONS AND Y you will be on your way. Enjoy!

Only 4 wires. For the model without external coil on the distributor. So only 4 wires. I hope it help.

Contrary to what has been posted previously, this item only has 3ft. of wires on each sensor. If you need sensors and replacement wires, you will need to purchase additional wire elsewhere for this to work. I had to return the item for exactly this reason - our wires are bad, and 3ft. of wire does me no good.

T suggest you either call Honeywell or log on to their web site where they will give the right info. I am using mine 240 volts@ 40 volts But every installation is different. You should of gotten that information on the base board. Good luck

It depends on the type of installation - single pole or 3-way and whether the switch is in the middle or the end of the run. Here is a link to the Honeywell Installation Guide showing drawings of each type of installation. https://customer.honeywell.com/resources/techlit/TechLitDocuments/69-0000s/69-2458EFS.pdf You can also call Tech support at 800 468-1502 and they'll walk you through the process. Good luck!

Don't know how to work with 2 wires. This switch took three wires: blue for load, black for hot line, and white for neutral line. You need to have three wires to make it work.

Thanks, for your question. The ones I purchased from Amazon I had installed by my Son so I could not honestly tell you why one would have 3 wires or two. Now, with that being said my home was built in 1995 so it's not that really old. I cam assuming that depending on how old or new is your home may make a difference. When I see three wire I think positive, negative and ground. A suggestion, you maybe able to connect the negative to the ground making two wires instead of three. Your neighbor if they have the same home chances are they may have change there also so they be of some help also. Good Luck.. Thanks, for your question.
